Ken, Just to clarify, you have your playback from HV20 set as DV output first? If so and you are still getting this message, I think it has to do with how Canon camcorder record. I ran into this with a friend of mine who own a GL2, does a regular recording, then try to play it back to a settop DVD recorder (not LG, but Proton or something like that) and got that message. I shared a tape that was recorded in my Vx2000 and he played back using varioius camcorders to the recorder and it was able to record. Weird, very weird. Perhaps, you should call Canon and ask them if there is a trick to the recording or playback.
